Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel related to power management (PM) within the regulator subsystem, specifically in the fp9931 hwmon read() function. If the regmap read() function fails, the code does not properly release a PM reference, leading to a PM reference leak. This occurs because pm runtime put autosuspend() is not called when an error is returned.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
